WALNUT RIDGE, Ark. (AP) - A 14-year-old northeast Arkansas girl who has been missing for more than two months has been found dead in a river, authorities said Monday.

The body found Saturday in the Black River was identified as that of Sidney Nicole Randall, of Walnut Ridge, Lawrence County Sheriff Jody Dotson said.

Sidney was last seen on March 9. Her stepfather, John Cornell, the prime suspect in her disappearance, was found dead two days later in an apparent suicide. Cornell died of a self-inflicted gunshot near a truck parked in a field in the Walnut Ridge area, according to the sheriff's office.

Walnut Ridge is about 130 miles northeast of Little Rock.

Details about how and when Sidney died have not been released, and autopsy results are pending.
